SMILE Dashboard

Run locally

This section describes how to run the dashboard backend and frontend locally without docker.

Pre-requisites

Make sure you have installed the following:

  • Node.js: 16.10.0
  • Yarn: 1.22.22

Tip: We recommend that you use nvm: Node Version Manager and yvm: Yarn Version Manager to switch between versions more easily.

Windows Tip: If you are developing on Windows, we recommend that you use Ubuntu / Windows Subsystem for Linux.

Pre-build Steps

If starting from a fresh build, pull dependencies by running yarn from the project root directory.

If running into build issues, try purging existing contents from all /node_modules directories in project.

rm -rf ./node_modules frontend/node_modules graphql-server/node_modules

Download the Oracle Instant Client

Note: Skip this step if you are using a MacBook machine with an M1 chip or newer. Visit this link for the latest supported systems.

The Oracle Instant Client allows us to connect to an Oracle database (CRDB) for MRN-CMO-DMP data. This enables the searching of PHI data on the Patients page of the dashboard.

Download the Oracle Instant Client from here.

Select the version corresponding to your operating system and download the latest version's Basic Package zip file.

Unzip and copy the entire directory to /graphql-server/opt/oracle or your preferred location.

Why can't we just use the Nodejs' oracledb package?

By default, node-oracledb runs in Thin mode (vs. Thick mode). The CRDB uses a password verifier type (0x939) that is not supported by Thin mode. Pairing the Oracle Instant Client with node-oracledb allows us enables Thick mode and allows us to connect to the CRDB.

Dashboard Backend

The backend for the dashboard is under ./graphql-server.

Set up your ./graphql-server/src/env/application.properties.EXAMPLE with all of the application properties needed for running the dashboard backend.

Add the following variable to your environment:

export NODE_TLS_REJECT_UNAUTHORIZED=0
export SMILE_CONFIG_HOME=[path to the dashboard configuration directory]
export SMILE_DATA_HOME=[path to the dashboard data directory]

# Skip if you skipped the Oracle Instant Client step
export LD_LIBRARY_PATH=[path to the Oracle Instant Client directory]

# Skip if you're not deploying the dashboard backend with Docker
export NODE_OPTIONS="--max-old-space-size=8192"

Build and launch the node app from the project root directory with:

yarn build:backend
yarn dev:backend

If successful, the graphql client should be available at https://localhost:4000/graphql.

Dashboard App

Set the following environment variables to point the web app to the React frontend and the Express backend, respectively.

Example:

export REACT_APP_REACT_SERVER_ORIGIN=https://localhost:3006
export REACT_APP_EXPRESS_SERVER_ORIGIN=https://localhost:4000

To run the frontend:

yarn dev:frontend

Example pages:

Tip: This page should open automatically through your default web browser. If not then please navigate to the web app manually.

Building the Docker Images

To build the frontend docker image:

docker build -f Dockerfile . -t [org]/smile-dashboard:[build version]

To build the backend docker image:

docker build -f graphql-server/Dockerfile . -t [org]/graphql-client:[build version]

Running with docker-compose

Running the dashboard backend and frontend with docker-compose.

Requirements:

  • ${SMILE_CONFIG_HOME}: path to the dashboard configuration directory
  • ${SMILE_CONFIG_HOME}/resources/smile-dashboard: path to application.properties and SSL cert files for the dashboard backend
  • ${SMILE_CONFIG_HOME}/nats: path to NATS config, must contain rootCA.pem

See ./server/env/application.properties.EXAMPLE for all of the application properties needed for running the dashboard.

Example docker-compose file contents:

version: '3'
